6 Claims. (Cl. 98-94) This invention relates to ventilators.

It is the object of the invention to provide a ventilator that is readily adapatable to different Windows in the same house or in any house where a ventilator can be used. The ventilator is readily adaptable for use at the upper end of the window frame or at the lower end of the window frame Where two sliding sashes are used. An arrangement is provided whereby the upper sash and the lower sash may be slid up and down notwithstanding the presence of the ventilator.

'I'he ventilator mounting along the upper sash is provided with means that may be attached to the upper sash whereby the upper' sash may be easily manipulated notwithstanding the fact that the ventilator is in place.

The mounting for the ventilator adjacent the lower sash is preferably placed at an angle of 10 so as to make more elcacious the pull of the Ventilator fan. The ventilator is a portable one with a. rotating fan operated by electric power.

Several mountings for the ventilator may be provided in diierent parts of the house and the one ventilator unit shifted from time to time to provide the requirements of any room. The ventilator has sliding frame members and glass panels which make it extensiblev in length to accommo- 1 date itself to varying window sizes.

In the drawings:

Fig. 1 is an elevational view showing the ventilator applied to the lower end of a window frame with asliding sash.

Figs. 2, 3, and 4 are sections on the corresponding section lines of Fig. 1.

Fig. 5 is a detail of the upper right hand corner of the ventilator unit showing some 4of the parts in section.

Figs. 6 and 7 are taken on the corresponding section lines of Fig. 5.

Fig. 8 is an elevational view showing the ventilator applied to the upper end of the window frame.

Fig. 9 is a section taken on the line 9-9 of Fig. 8 showing the fan unit turned back on its hinge mounting.

Fig. 10 is a. vertical section through the upper part of the window frame with the ventilator removed showing the mounting bracket.

Fig. 11 is a section taken on line 11-11 of 50 Fig. 10.

a designates a solid metal frame in the form of a casting which is provided with an annular vboss b which supports the swinging spider c (Fig. 9) by means of a hinge pin d. This spider has clamped thereto the electric motor e which serves to rotate the exhaust fan f. A relatively coarse mesh screen g can be clamped to the annular boss of the frame by means of the set screws h (Fig. 4). 'Ihis screen is supported in a conical spider i and carries a perforated cap y that covers the end 6 of the electric motor.

Anchored to the frame a at top and bottom are a pair of slide rods 1c 1c (Figs. 2 and 5). Sleeved over the ends of these slide rods are the incomplete sleeves Am. These sleeves are open for less than to straddle the two panels of glass 11. and o (compare Figs. 5 and 4) The rods k are correspondingly grooved as at p (Fig. 5) to straddle the glass panels n and o which slide by each other (compare Figs. 5 and 4) The glass panel n is sel5 cured to the ventilator frame a and the glass panel o is secured to the upright frame bars or Stiles q which in turn are secured by screws 1' to the incomplete sleeves m (shown in Fig. 5). The center ventilator frame a and the rods 1c combine with the incomplete sleeves m, the Stiles q, and the overlapping glass panels n and o to form the extensible ventilator unit that can be elongated or shortened at will to adjust it to varying widths of windows. Glass panels avoid the shutting ofi of light which would otherwise take place in the y ordinary ventilator installation.

Looking at Figs. 2 and 3 it will be seen that the ventilator is mounted at an angle of about 10 from the vertical tilting at its top outwardly these 10. This turns the axis of the fan up slightly so as to put the line of the suction slightly upward and thereby makes the fan more ecacious in sucking out the foul air that accumulates in kitchens, bath rooms, or other rooms. I find that this angle is Very desirable. The 10 angle brackets are simply angle irons or triangular brackets s secured to the lwindow frame on mounting just to the inside of the sash runway as is plainly shown in Figs. 2 and 3. The extensible vand portable ventilator. unit is drawn out to the correct length and is then simply seated in these brackets and the set screws t screwed in place; there are four of these. This placing of the ventilator and its brackets in no way interferes with the lower sash sliding up and down.

'Iurning to Figs. 8-11, it will be seen that the portable ventilator unit may be mounted at the top of the window frame vby means of the slightly different bracket which is best seen in Fig. 10 and designated u. This bracket is provided with a cradle v to take the lower bar or incomplete sleeves m of the extensible ventilator unit. The mounting is effected in the same way by pulling the slides out or pushing them in to get the correct length of 5,5

the portable unit; then lifting it up. and dropping the ventilator unit into the two cradles of the bracket. The set screws t are then put in place and screwed in. This holds the unit at the top of the window frame. The upper sash is pulled down to substantially register with the lower frame member of the portable unit.

When the ventilator is not being operated, it will be desirable to close the sash by sliding it past the ventilator unit. This is easily done with the lower sash as it can be manipulated with the upper or meeting rail of the lower sash. Ordinarily it would be pretty hard to manipulate the upper .sash because the lower-sash rail is to the outside of the lower sash. I have overcome this dilculty by a special arrangement-my upper mounting brackets u. It will be noticed that the mounting bracket has the greatest part of its length slightly offset beginning with the shoulders :c (see Figs. 10 and 8) The purpose of this is to present a narrow runway between the bracket and the side of the window frame to accommodate the arm y (Figs. 10 and 11) This arm has its inner end bent in and secured tothe window sash by a screw z (Fig. l1). The outer end offthese two arms (there would be one for each side of the window) is provided with a notch in which are engaged the hooks of the window sticks. These sticks may be considered a part of the ventilator unit and are used to pull the sash down, or used to push the sash up as desired.

What I claim is:

1. A portable ventilator for windows comprising in combination brackets adapted to be secured to opposite parts of a window frame and clear of the window runway, each bracket having a flange inclined upwardly and outwardly, a ventilator unit having a power driven fan and having sections slidable relative to each other for adjustment to the window width, and having end parts adapted to lie substantially iiush against the flanges of the brackets with the ventilator'tipped at an angle substantially correspondingfto' said anges, and means detachably securing the ventilator to the brackets.

2. A window ventilator construction comprising in combination brackets for supporting a ventilator adjacent the upper end of a window frame of a two-sash sliding window with the ventilator extending across the frame, said brackets having portions lying ush against the frame and portions spaced therefrom to provide a space between each bracket and the adjacent side of the frame, said brackets and ventilator being positioned near the top of the window frame, a pair of arms secured to the upper sash and each arm extending through one of the said spaces, said arms serving as a means for sliding the upper sash in its runway with said arms sliding in said spaces.

3. A portable ventilator unit in combination with brackets that can be secured to the side of the window frame adjacent the upper end thereof in a two-sliding sash window, said brackets having olfset portions, and arms arranged to move in the space between the offsets and the window frame and be secured to the upper sliding sash.

4. In a ventilator for house windows, a ventilator unit that may be tted in the window frame and including a frame for the ventilator opening, said frame having a boss, a fan support in the form of a spider hinged to the said frame, a fan andl motor carried bysaid support that may be turned down with the support, and a removable conical screen frame arranged to be clamped over the boss and over the fan motor and support.

5. A ventilator for windows', comprising a ventilator unit adapted to be fitted into and secured to a window frame and including a substantially circular ventilator opening, an annular boss defining the opening, a fan and motor support in the form of a spider carrying the fan and motor at its central portion, means hingedly connecting the support to the ventilator unit whereby the support, motor, and fan may be hinged into and out of operative relation with the opening, a conical shaped screen, a supporting frame therefor having a circular rim adapted to it the annular boss, and means for detachably securing the screen and supporting frame in place over the opening.

6. A power ventilator for windows, comprising a center frame member having a Ventilating aperture therein, means for mounting an electric motor and air fan in axial alignment vwith the ventilating opening, a pair of rods one carried at the top of the center frame member and one carried at the bottom of the center frame member, said rods each projecting at opposite ends away from the center frame member, said rods having lengthwise extending grooves, a pair of glass panels mounted to the center frame member, and each having its top and bottom edges confined in the grooves of the rods, said grooves having a width greater than the thickness of the glass panels and the glass panels being disposed along one side of the grooves, a pair of end members, each end member having a pair of slotted tubes secured thereto and projecting therefrom and said tubes telescoping over the projecting ends of said rods, a glass panel secured to each end member and each glass panel having its upper and lower edges coniined in the slotted tubes, the slots in the tubes having a width sufficient to accommodate the thickness of two overlapping glass panels and the glass panels secured to the end members being positioned adjacent one edge of the slots in the tubes whereby the glass panels on the end members lie in a plane removed from that of the glass panels of the center member whereby the glass panels on the end members may overlap in sliding relation to the glass panels carried by the center member, brackets adapted to be secured to opposite sides of the wiindow frame, and means for attaching the end members to opposite brackets.
